The KYN28A-12/24(Z) indoor AC metal-clad switchgear, widely recognized as the cabinet, is designed to operate within a voltage range of 3.6-24KV for three-phase AC 50HZ single busbar systems and single busbar segmentation systems. This advanced power distribution equipment is predominantly utilized in power plants, substations, industrial and mining enterprises, high-rise buildings, and diverse environments for the efficient reception and distribution of power. It also plays a crucial role in circuit control, protection, and monitoring.
Our product's circuit breaker features a versatile middle mounting mode, offering the option to select between VS1 (ZN63A) type or VD4 type vacuum circuit breakers. Moreover, it supports a broad spectrum of vacuum circuit breakers from an array of domestic and international specifications and models.
Complies with standards: GB3906-2006 "3.6kV~40.5kV AC metal-enclosed switchgear and control equipment," DL404-2007 "Indoor AC high-voltage switchgear ordering technical conditions," and IEC298 (1990) "Rated voltage above 1KV and below 52KV AC metal-enclosed switchgear and control equipment."
